-
functional disorders
- when vocal quality deteriorates in the absence of anatomic and neurological factors, there may be a functional disorder
- nothing looks wrong with them
-
functional dysphonia
- symptoms will come and go
- treat with laryngeal massage
- more common in women
-
mutational falsetto and juvenile voice
- usually in men
- when a boy's voice changes during puberty, the structure changes
- they speak really high
- can be treated by laryngeal massage
-
neurogenic disorders
- Vagus Nerve Lesion
- Spasmodic dysphonia
- ALS
- Parkinson's
- latrogenic etiology
- Vocal tic, Tourette Syndrome
-
what if you can't use the larynx?
-
assessment for larynx
- Strobe
- Oral peripheral
- Medical referral
- Case history
- Clinical observation
- Listen for quality, loudness, pitch, etc.
-
Things to do for nodules, polyps, granulomas
- respiration- adequate breath support
- relaxation training
-
Things to stop doing for nodules, polyps, granulomas
- limit vocal abuse
- stop yelling, screaming, anything done with
- excess tension
- reduce loudness
- stop smoke exposure
- drinking is bad too
- granulomas- diet and medication for GERD
-
surgery for vocal nodules/polyps
- iffy
- difficult
- must have SLP as well, or precipitating
- factors will still be there
-
different treatments for neurogenic disorders
- botox for spasmodic dysphonia
- other meds for other conditions
-
what is voice?
- phonation
- resonance
- frequency
- intensity
-
phonation
producing sound by sending air through vocal folds
-
resonance
what happens to shape or sound after its produced in vocal folds
-
frequency
- the number of times the vocal folds oscillate
- the more they vibrate- the higher our pitch
- the less they vibrate- the lower our pitch
-
intensity
how much air we send through those vocal folds; how loud
-
habitual pitch
- normal pitch
- you use it the most
-
optimal pitch
the most healthy pitch for a person to use
-
basal pitch
lowest pitch your voice can produce
-
ceiling pitch
highest pitch your voice can produce
-
vocal range
difference between ceiling and basal pitch
-
loudness
- determined by volume
- can be too loud (yelling)
- can be too soft
-
voice disorders
voice differs in pitch, loudness, and/or quality compared to persons of a similar age, background, race, ethnicity to the extent that it calls negative attention to the speaker and/or interferes with communication
-
___ in 100 people will have a voice disorder at some poing
6
-
__ % of people may have voice problems in their life
29%
-
voice disorders are higher in ___ than in ___
women; men (7% vs 5%)
-
most common causes of voice disorders
- vocal nodules 22%
- edema 14%
- polyps 11%
- carcinoma 10%
- vocal fold paralysis 8%
- unknown 10%
- other stuff
-
voice disorders found in kids as well
- 4-6% of kids have some
- problems with voice
- most common cause vocal nodules
- more than 1 million kids develop nodules annually
-
phonatory quality (disturbances)
- hard glottal attack
- glottal fry (tightly
- approximated folds)
- breathy phonation (aphonia)
- spasticity or strain (too much tension, stoppage)
- diplophonia- random pitch breaks
- hoarseness (noise introduced-lose higher frequencies)- strain+breathiness
-
types of voice disorders
- structural- when something is wrong in the vocal folds
- functional- in the way you use your voice
- neurogenic- neurological cause for voice disorder
-
vocal nodules- what are they?
- What are they?
- -small, bilateral, callous growths or protuberances on inner edges of vocal folds
- you can't do surgery on them
- bilateral
- sounds scratchy
-
what causes vocal nodules?
- vocal abuse
- over singing
- singing the wrong way
- yelling, screaming, cheering, etc.
- basically, too much tension, hard attacks
- talking or yelling when you have a cold, etc.
-
what goes wrong?- vocal polyps
- unilateral
- can do surgery
- tend to be more
- vascular
- broad term for a "protruding growth from a mucous membrane" (Dorland's 1988)
- change mass of folds
- may change approximation
- hoarse, breathy voice
- fold polyps
-
contact ulcers and granulomas
- contact ulcers are inflamed lesions or ulcers
- posterior part of pharynx on arytenoid cartilages-sores
-
causes of contact ulcers and granulomas
- forceful contact (repeated), tissue dies
- body forms a granuloma at site of ulcer
- folds can't approximate- no smooth surface
- may result from GERD (gastroesophageal reflux disease)- acid reflux, heartburn- acid backs up into esophagus
